Juicy 7 lever problems

I have had Avid Juicy 7 brakes on my Santa Cruz Blur since it was new, September 2005. They are noisy brakes but work well. Recently the bike took a tumble and the housing at the left lever got deflected at about 90 degrees. Yesterday, on a ride, I noticed that the left lever was slack - it wouldn't return after being squeezed. It felt like it had play before it began to compress the cylinder.
